PICKER-ACTIGN FOR LOOMS.

Application filed April 5,

To all whom t may concern:

Be it known that I, Ammann B. SiMoNnAU, a citizen. of the United States,residing at Waterville, in the county et Kennebec and State ot Maine,have invented certain new and useful Improvements in PickersActions lorLooms, of which the following is a specification. y

This invention relates to picker actions for looms and has for an objectto provide means for actuating the picker from the oscillation of thelay imparting to the pickors the mucl1-tobe-desired quickness anddecisiveness of impulse `lor actuating the shuttle.

The further object of the invention is to provide a cam rotated with astep-by-step movement from the lay, such cam actuating a system oitlevers which impart the required motion to the pickers alternately atopposite ends ot the lay.

lilith these and otherI ,objects in view the device comprises certainnovel elements, units and combinations as will be hereinafter more fullydescribed and claimed.

In the drawings,

Figure 1 is a view of a conventional loom shown in rear elevationshowing the picker actuating mechanism.

Fig. 2 is a top plan view of so much of the loom as may be necessary toshow the action, the superstructure being broken away.

Fig. 3 is a vertical sectional view taken on line 3 3 of Figs. 1 and 2showing the cam and the means of actuating the same trom the oscillationof the lay.

Fig. f1 is a view on the same plane as Fig. 3 with the lay advanced tobegin the turning of the cam.

Fig. 5 is a View on the same plane as Figs. 3 and l with the layadvanced to its limit and the cam completely turned a quarter of arevolution.

Like characters of reference indicate corresponding parts throughout theseveral views.

The improved picker action which forms the subject matter ot thisapplication is adapted to operate in conjunction with looms of varioustypes, as for instance the loom disclosed in co-pending applicationSerial Number 352,438 filed January 19, 1920, but it is to be understoodthat it is not in any way limited to coaction with that identical loom.

Specification of Letters atent.

1920. Serial No. 371,422.

A conventional loom iframe 10 supports Va lay of substantially the usualand ordinary type pivoted at 11 and carrying a reed 12 a shuttle raceand shuttle boxes 13. Operating also with the lay are pickers 1d and 15in substantially the usual vand ordinary manner, so far as theirtraveling with the lay is concerned or their relation to the shuttlerace.

To the pickers 1.4L and 15 cables lG and 17 are secured, passing overpulleys 18 and 19 respectively, and connected with levers 20 and 21.

At the rear of the lay a cam member 22V is journaled being preferablysquare through the major portion oi its length and provided with an arm23 held by the spring 241; upon the squared portion of the cam member 22whereby the said member is held. against rotation until rotated bymechanism provided for that purpose. The mechanism tor rotating themember 22 comprises a detent 25 pivoted to the lay at 26, and engagingratchet teeth 27 'formed in the member 22. The detent 25 is controlledby the spring`28. The detent 25 is provided with spaced teeth orshoulders 29 and 30, pro erly proportioned and spaced to engage t eratchet teeth 27 when the cam member 22 rotates.

The position of attaching the 1 detent 25 to the lay is such that theswing of the lay, through its complete cycle, moves the detent 25 asufficient distance to rotate the member 22 one quarter of a revolution.As shownv at Fig. 3 the lay is in. its extreme forward position. Uponstarting to the rear the tooth 29 engages one oi the teeth and moves themember 22 upon its journal as indicated at Fig. l until the tooth 30engages the next succeeding tooth 27 whereupon the completion of themovement of the lay completes the one quarter revolution of the member22, as indicated at Fig. 5.

The rotation of the member 22 is trans lated into picker actuatingmotion by em ploying cam sections 31 and 32 engaging against strikers 33and 34, respectively. The

strikers 33 and 34 extend upwardly and bear 105 upon the levers 2() and21. As the member 22 is rotated by the oscillation of the lay the cams31 and 32 alternately depress the strikers 33 and 34. The depression ofthese strikers actuating the levers 20 and 21, re- 11G spectively, actthrough the cables 16 and 17 to actuate the pickers 111 and 15. Springs35 and 36 are employed to return the pickers lll and l to the outerlimit of their movements also serving to raise the levers 2() and 2l andthe strikers 33 and 34 When the lattter are released by the furtherrotation of the cam member 22.

It Will be apparent, therefore, that at each oscillation of the lay themember 22 is given one quarter of a revolution, changing the relativepositions oic the cams 3l and 32, and, likewise, the relative positionsof the Vstrikers 33' and 34. The change of such positions of thestrikers actuates the pickers to impart to the shuttle the requiredmovement in the usual Well-known manner.

Having thus fully described my said invention What claim as new anddesire to secure by Letters Patent is:

l. The combination with a loom embodying` Aan oscillating lay andpickers carried thereby, a cam member journaled adjacent the lay,strikers associated With the cam member adapted to be alternatelydepressed Yby the cams, means transmitting motionL from the strikers tothe pickers comprising levers on the layv adapted to be depressed by thestrikers and means carried by the lay for rotating the cam member {vit-ha step-by-step movement.

2. The combination with a loom embodying` an oscillating lay and pickerscarried thereby, or a cam member jonrnaled adjacent the lay, means toretard rotative movement of the cam member, strikers positioned to bealternately depressed by the eam member, levers connected n'ith thepickers and positioned to be struck by the strikers and means caried bythe lay to rotate the cam member with a step-by-step movement.

3. The combination with a loom embodying an oscillating lay and pickerscarried thereby, pivoted levers connected with the pickers, strilrerspositioned to alternately strike and depress the levers, a memberionrnaled adjacent thc lay, cams carried by the jonrnaled memberoperating` npon the strikers and pawl and ratchet aetions between thelay and journaled member whereby oscillation of the lay is translatedinto step-by-step rotative movement ot the Jiournaled member.

In Witness whereof: l have hereunto set my hand and seat at Vaterville,Maine` this first day of April, A. D. nineteen hundred and twenty.
